Should the outlet tee extend to the bottom of the tank?

The outlet tee should not extend to the bottom of the tank because doing so could create issues with maintaining proper water quality and reducing the likelihood of sediment disturbance. When the outlet tee is positioned above the bottom, it helps prevent sediment from being drawn into the system, which is essential for the efficient functioning of various wastewater systems.

If the outlet tee were to reach the bottom, it could potentially suck up debris and solids that have settled, leading to clogs or other malfunctions in the system. Hence, keeping the outlet tee above the tank’s bottom is a design practice that supports better function and longevity of the system.

Regarding the other options, while it might seem logical to position the outlet tee differently based on tank depth or considering specific types of tanks, best practices generally recommend the position above the bottom regardless of these factors.
